Carbon dioxide activation as an η1-C metallocarboxylate: metallocarboxylate ester derivatives as a C1 template in co-ordinated ligand reactions
Abstract
In tetrahydrofuran the reaction between Fp2Mg [Fp = Fe(CO)2(η-C5H5)] and CO2 gives the symmetrical metallocarboxylate (FpCO2)2Mg, which can be alkylated to give the ester FpCO2Me; its activated ester FpC(OMe)2+ serves as a C1 template for reduction to FpCH2OMe.
